Claims. (Cl. 4-102) This invention relates to certain new and usefulimprovements in toilet fixtures and has for a special object to producea urinal particularly designed for use by women, and so constructed thatwhen so used it is hygienic, sanitary, and safe and aids in theprevention of the spread of diseases even when installed for use in apublic toilet.

A further object resides in the provision of a urinal which may beeasily and conveniently used by women without the necessity or danger ofthe user touching or contacting any portion of the urinal with theconcurrent rlsk of transferring disease germs or bacteria from one userto another.

A still further object is to produce a fixture of the type designatedwherein the water-delivery nozzles or apertures thereof are so located,arranged and constructed as to accomplish complete flushing of allportions of the receptacle forming a part of the fixture, and also acomplete and adequate washing of all portions of the inner wall or wallsof the receptacle.

A still further object is to produce a fixture of the type indicatedwhich is provided with a forwardly projecting, relatively long andnarrow extension capable of being easily and readily straddled while theuser of the urinal occupies a squatting position, and which forms a partof the receptacle portion of the fixture and receives flushing waterunder conditions such as to create a sweeping flow diagonally across thebottom thereof and across all portions of the upright wall or wallsthereof.

A further object is to provide such a fixture in which the receptacleportion thereof consists of two well defined parts, viz., a bowl whichapproximates a portion of a sphere and a forwardly projecting extensionwhich approximates a narrow, relatively long and shallow channel in opencommunication with the bowl.

A further object is to produce a fixture of the type indicated whichconsists essentially of an open top recep tacle consisting of a bowl anda relatively narrow pan to both portions of which flushing water is sodelivered as to completely flush and evacuate the pan while maintaininga swirling movement of the flushing water within the bowl and underconditions such as to form a vortex adjacent the bottom of the bowl.

A further object is to provide a fixture of the type indicated whichincludes as a part thereof an open top receptacle consisting essentiallyof a bowl and a pan and which is provided with means for simultaneouslydelivering flushing water to both the bowl and pan under conditions suchas to create a vortex action within the bowl which is supplemented tosome extent by the movement of flushing water from the pan into thebowl.

A further object is to provide means for elfectively and completelyflushing a fixture of the type here indicated which is provided with anopen top receptacle made up of a bowl shaped portion and a relativelylong narrow and shallow extension which communicates with the bowlshaped portion above the bottom thereof.

These and other objects are attained by means of a fixture having thestructural and functional features herein described and illustrated inthe accompanying drawings. In the drawings,

Figure 8 is a front elevation of the fixture shown in Figure 7, andFigure 9 is a side elevation of the fixture shown in Figures 7 and 8.

All the figures except Figures 6, 7, 8 and 9 are shown in connectionwith arrows in an attempt to indicate the flow lines of flushing waterdelivered to and passing through the water-receiving and deliverypassages of the fixture during a flushing operation.

The illustrated embodiment of our invention consists of a speciallyformed water closet in which the water delivery passages, apertures andjets are so formed, positioned and arranged as to accomplish aneffective flushing and washing of all interior surfaces of thereceptacle forming a part of the closet. This receptacle is somewhatsimilar to the usual closet bowls in that it is provided with a supportwhich is formed as an integral part of the wall of the receptacle. Whilethe receptacle is similar in some respects to the more or less standardforms of closet bowls, it is of such shape that it is capable of beingreadily and effectively utilized for the purpose intended.

In the embodiment illustrated, the receptacle portion of the fixture ismade up of two essentially distinct parts which, however, merge to forma unitary, open top receptacle, which in plan view appears toapproximate the shape of the old conventional form of keyhole. As tothis see the plan views of Figures 2 and 7. This characteristic shape isdue to the fact that the forward portion of the receptacle consists of arelatively long, narrow and incidently a relatively shallow channelshape portion 7, whereas the rear portion 8 is generally bowl shape. Thewalls of both the portions 7 and 8 are such as to produce a receptaclewhich is characterized by streamlined surfaces. In addition, the twoportions, 7 and 8, are so arranged that their internal surfaces mergeunder conditions such that the entire interior of the receptacleconstitutes flow-directing surfaces which are devoid of flow-disturbingangles, ridges or shoulders. The external surface of the receptacleportion of the fixture is similar to the internal surface in that it isfree of projecting shoulders, ribs and corners.

The channel shaped portion 7 of the receptacle, may be moreappropriately designated as the receiver or pan. In the illustratedembodiment it is about seven inches wide and is of a length which ismore than once and a half its width. Its internal width is about sixinches. The upper edge of the pan is about 18 inches above thesupporting floor and the entire space below and 'on both sides of theportion 7 is free and unobstructed and, therefore, provides free accessto the fixture and adequate foot space for the user of the urinal. Thereceptacle is provided with a water-delivery rim or trough 9 which is soformed as to provide a continuous water-delivery conduit or passagearound the entire upper edge of the receptacle. This trough 9 over-hangsthe interior of the receptacle and its bottom wall is so punched as toprovide several series of water-delivery jets or apertures so locatedand arranged as to deliver flushing water into the receptacle and ontoand across substantially the entire inner surface thereof.

In the illustrated embodiment the upper edge of all portions of theextension or pan 7 is horizontal, consequently the upper surface of thetrough 9, contiguous with the pan, extends in a general horizontaldirection except that it is downwardly inclined inwardly of thereceptacle, as shown in the sectional view of Figure 5. This inclinationis preferably carried out throughout the entire extent of the trough.

The bowl 8, which constitutes the rear portion of the receptacle, is ofa form such that at least a part thereof approximates a portion of asphere. In the illustrated embodiment, the plan view of the receptacleindicates the rim of the bowl as an arc of a circle of about 240degrees. The rearmost portion of the wall of the bowl 8 is, however,elevated substantially above the upper edge of the pan 7. This part ofthe wall extends upwardly to a substantially horizontal portion about 5above the trough surrounding the pan 7. As a result, the trough 9associated with the rear wall of the bowl, is elevated and, as shown inFigures 1, 2, 7 and 8 of the drawings, extends in a substantiallyhorizontal direction throughout a circular are about 120 in length. Theportions of the trough 9, intervening between the rearmost portion ofthe bowl 8 and the rim or trough of the pan, are downwardly curved so asto merge with the portion of the trough surrounding the pan withoutinterposing, blocking or impeding surfaces which will hinder or retardthe flow of water through the trough and into the portion thereof at thefront of the pan 7. It will be understood that the internal surface andconsequently the wall of the bowl 8, follows the curvature of theportion of the trough associated with it, except that the wall convergesdownwardly and terminates in a trap 10.

The bowl portion of the receptacle is somewhat smaller than the bowls ofmodern water closets. The internal diameter (maximum internal width) ofthe bowl forming a part of the illustrated embodiment, is approximatelyequal to the maximum internal length of the pan 7. In view of the factthat there is no clear line of demarkation between the pan and the bowlit may be stated that the maximum internal width of the bowl is slightlygreater than the maximum internal length of the pan.

In the illustrated embodiment, a pedestal 11 constitutes the supportportion of the fixture. similar in many respects to pedestals which formparts of modern closest bowls, in that it includes within its make-upthe trap and a siphon 12. The upleg 13 of the siphon communicates withthe trap and the downleg 14 terminates in a port 15 which is adapted tocommunicate with a soil pipe, not shown. The port 15 is oifset-withrelation to the major portion of the downleg 14-by means of a horizontalshelf 16. The upper portion of the pedestal is shown as having awaterreceiving chamber or passage 17 formed therein which is providedwith an inlet port 18 adapted to communicate with a source of waterunder pressure such as piping 19 illustrated in Figures 1, 2, 7, 8 and 9of the drawings.

The passage 17 communicates with the water passage of the trough 9,through an outlet port 21. It also communicates directly with a jetdelivery passage 22 formed in, or immediately adjacent to the rear wallof the bowl 8. This passage 22 is adapted to deliver flushing liquid inthe form of an upwardly directed jet into the up-leg 13 of the siphon.The siphon jet is delivered through an aperture or nozzle 23appropriately located within the up-leg 13. All these pedestal passagesand connections are more or less conventional. They contribute to theflushing operation of a fixture embodying our invention in substantiallythe same manner that they contribute to the flushing of an ordinarycloset.

It will, however, be apparent that the operation of flushing and ofwashing the surfaces of the pan 7 and the bowl 8 of a fixture such as isdisclosed in the drawings, involves a problem. The flushing liquid mustbe so delivered-from the standpoint of surface coverage and rate offiow-that it will effectively flush the receptacle and wash all portionsof the walls of the receptacle, but at the same time avoid splashingsuch as would be detrimental to the use of the receptacle. When theflushing operation is completed the pan 7 and the bowl 8 must notcontain contaminated water. The problem involved by the flushingoperation is occasioned by the fact that the pan is long and narrow andits internal width, at the zone of junction with the bowl, isapproximately half the maximum internal width of the bowl.

The normal water level within the receptacle is designated by thedot-dash line 24, it being apparent that the tip of the partition 25establishes the normal water level. This partition 25 is formed withinthe pedestal and separates the up-leg 13 from the down-leg 14 of thesiphon. With the water level as indicated, it is apparent that theflushing operation must be such as to not only move a substantial amountof water out of the receptacle but also replace the same with clean oruncontaminated water. To accomplish this it is desirable to deliverflushing water simultaneously to the jet nozzle 23 and thewater-delivery ports or apertures of the trough 9.

As is usual practice, the jet issuing from the nozzle 23 must be such asto effectively initiate an upward flow of This pedestal is the waterwithin the up-leg 13 of the siphon, and maintain such a flow at leastuntil a siphon action is set up within the passages 13 and '14. It isalso desirable to so deliver the water from the trough to the bowl 8 asto initiate a swirling action within the bowl under conditions such thata whirling funnel-like formation or sheet of water moves downwardlyalong the walls of the bowl with its vortex disposed in the trap 10adjacent the inlet to the up-leg of the siphon. This not onlycontributes to the effectiveness of the siphonic action but it increasesthe wall washing eifectiveness of the water issuing from the trough 9.

It is apparent that at the beginning of a flushing operation asubstantial amount of water is located within the confines of thechannel shape pan 7. This water must not only be flushed out of the panbut its complete removal from the pan must be accomplished early in theflushing operation so that the walls and floor of the pan will bethorough and adequately washed by a free flow of uncontaminated water.While the flushing and adequate washing of a narrow channel such as thepan 7 occasions some difliculty, the real problem is to so discharge thewater from the pan during the flushing operation that it will merge withthe swirling sheet of water within the bowl 8 without creatingturbulence or splashing such as will cause drops or particles of waterto rise above the edge of the receptacle. Thus it is essential to sodeliver water from the pan 7 into the bowl that it contributes to themovement of the whirling sheet of water, which is initiated by theapertures of the portion of the trough 9 surrounding the bowl 8.

In order to accomplish all this, i. e., to accomplish a completeflushing of the receptacle and an adequate washing of all portions ofthe wall thereof, we have employed a special arrangement of troughdelivery nozzles or apertures which involves the use of at least fivedifferent groups or series of such apertures. As is more or lessconventional in the modern water closet, the trough apertures are formedin the lower wall of the trough and are so positioned as to direct thewater issuing from them onto adjacent surfaces of the wall of thereceptacle. Trough apertures 26 may be designated as constituting thefirst series. As shown in Figures 2, 3 and 6, these apertures are sopositioned and so inclined that they not only deliver water from thetrough 9 onto the inner surface of the bowl 8, but so deliver it thatthe water is caused to traverse the surface of the bowl in a spiraldirection. The direction of movement of the spiral sheet of water isdownward and counter-clockwise.

In Figures 2, 4 and 6, a single water-delivery aperture 26' is shownbetween the apertures 26 and the second series of apertures 27. Theaperture 26' is smaller than the apertures 26 but larger than theapertures 27. It is so positioned as to deliver water verticallydownward across the portion of the surface of the bowl 8 which isimmediately adjacent to the rear end of the pan 7. The apertures 27 areshown in Figures 2 and 6, one such aperture being shown in Figure 4. Theapertures 27 are spaced along one side wall of the pan 7 and are solocated and inclined as to deliver water onto the adjacent wall of thepan in a direction such that it moves obliquely (downwardly andrearwardly), i. e., toward the bottom of the pan and also toward thebowl 8. These apertures are of less diameter than the apertures 26, andat the rear or bowl end of the pan, their spacing is somewhat greaterthan that of the apertures 26. This spacing, however, decreases towardthe forward end of the pan.

A single apenture 27 is located between the apertures 27 and a thirdseries of apertures, viz., apertures 28. Aperture 27', like aperture26', is so positioned that it merely delivers a downward flow of wateracross the inner face of the adjacent portion of the wall of thereceptacle. It is of somewhat smaller diameter than the apertures 27.

The apertures 28 are located in the forward portion of the trough 9 atone side of the center line of the trough, i. e., of the longitudinalaxis of the pan 7. They are of larger diameter, and consequently ofgreater water-delivery capacity, than any of the other water-deliveryapertures of the trough. They are closely spaced and are so located thatthey deliver water vertically downward across the inner surface of halfthe forward wall of the pan and also across that portion of the innersurface which intervenes between the forward wall and the adjacent sidewall of the pan. This side wall of the pan is located on the oncomingside of the pan, from the standpoint of the movement of the swirlingsheet of water passing downwardly across the surfiace of the bowl 8. Itis designated by A in Figures 2, 7 and 8 of the drawings.

The fourth series includes the apertures 29. These are the smallest ofall the water-delivery apertures of the trough. They are illustrated inFigures 2, 5 and 6 of the drawings, are relatively widely spaced and arelocated on the opposite side of the center line of the trough from theapertures 28. They are so disposed as to deliver water verticallydownward across half of the front wall of the pan and also the curveportion of the wall of the pan which connects the front wall with thelateral wall designated by B in the drawings. The wall B is opposite tothe wall A and is the lateral wall away from which the swirling sheet ofwater moves as it traverses the surfiace of the bowl 8, i. e., the wallfrom which the counter-clockwise flow recedes as it moves from thetrough 9 downwardly toward the trap 10 at the bottom of the bowl.

The fifth series of apertures includes the apertures 30. Their positionand inclination with relation to the wall B corresponds to the positionand inclination of the apertures 27 with relation to the wall A. Theyare shown a slightly larger than the apertures 27 and they deliver waterobliquely across the inner surface of the wall B with the result thatthe water so delivered is directed toward the rear end of the pan 7, i.e., toward the bowl 8.

As indicated by the arrows of Figures 1 and 2, the water delivered fromthe trough 9 to the interior of the receptacle occasions a swirling flowwithin the bowl 8 and a predominantly diagonal flow across the floor ofthe pan 7 and in a direction such that on leaving the pan and enteringthe bowl it augments, or tends to augment, the swirling movement of thewater within the bowl.

All this is accomplished by properly positioning the various series ofapertures and by so proportioning the size, number and spacing of theapertures that they c'ooperate without occasioning undue turbulence orsplash ing. As to this it is apparent that the series of apertures 26which partially surround the bowl 8, are the swirlproducing apertures.They are so proportioned as to size, spacing and number as to deliversuflicient water to the bowl to accomplish an adequate washing of thewalls of the bowl, contribute to the complete flushing of the receptacleand create a well defined vortex at the bottom of the bowl.

The apertures 28 constitute the pan-evacuating series. They are also sopositioned as to at least initiate a diagonal flow of water across theslightly inclined floor of the pan 7. They, therefore, may be termedevacuating and flow-directing apertures. As to the direction of Walterflow within the pan, it must be borne in mind that the series ofapertures 27 plays an important part in creating and maintaining thediagonal direction of flow of the water issuing from the nozzles 28. Aspointed out, the

apertures 27 are rearwardly inclined so that they initiate a rearward aswell as a downward flow of the water issuing from them. They areapertures of relatively large diameter and their spacing decreasestoward the forward end of the pan. The increase in flow occasioned bythis change in spacing, and the inward convergence of the wall A towardthe bottom of the pan, occasions a crowding action on the part of thewater delivered from the apertures 27 and consequently all theseapertures to some extent contribute to deflecting the how of the largeramount of water issuing from the apertures 28, so that it movesdiagonally across the bottom of the pan. It may, therefore, be said thatthe apertures 27 are auxiliary flow-directing apertures.

In referring to the functional effect of the apertures 27 and 28 it mustbe borne in mind that the aperture 26' contributes to a non-splashingunion or merging of the water issuing from the adjacent apertures 26 and27. Thus the downwardly directed water from the aperture 26' isinfluenced by, and has an influencing effect upon the water issuing fromthe adjacent aperture 26. It also has an influencing effect on the waterissuing from the rearwardly directed adjacent aperture 27, with theresult that the water from all three apertures tends to move ingenerally the same direction in passing over adjacent portions of theinner wall of the receptacle. This minimizes turbulence, reduces thetendency toward splashing and contributes to the swirling action of thewater moving toward the bottom of the bowl 8. Thus the single aperture26' has a harmonizing effect on the flow issuing from the adjacentapertures 26 and 27.

The single aperture 27 washes the inner face of the portion of the panwall intervening between the series of apertures 27 and 28. It tends toharmonize the flow issuing from these two series of apertures. Itdelivers a lesser amount of water than that delivered by each of theadjacent apertures 27 and 28. It, nevertheless, covers the surface ofthe front wall of the pan located between the apertures 27 and 28, andcontributes to the flow-directing effect of the apertures 27 on thewater issuing from the apertures 28.

The apertures 29 are in eflect fill-in apertures. They are soproportioned as to size and spacing that they merely deliver enoughwater into the pan to adequately wash the adjacent inner wall thereofand at the same time hamper undue spreading of the wa ter issuing fromthe apertnres 28. Thus, while they contribute to the delivery offlushing water to the receptacle, they do not impede nor hamper thediagonal flow across the bottom of the pan of the water issuing from theapertures 28.

The apertures 30, like the apertures 27, are so positioned and are ofsuch size and spacing as to adequately wash the adjacent wall of the panand also contribute to the rearward movement of the water traversing thepan. The rearward inclination of the single aperture 30, which isadjacent the rear end of the pan and consequently adjacent one of theports 26, contributes to the harmony of fiow of the water issuing fromthe pan and the water traversing the bowl. Thus it is apparent that eachof the trough apertures cooperates with every other trough aperture inproducing a substantially non-turbulent and nonsplashing flow of waterinto, through and out of the receptacle during flushing operations.

In Figures 7, 8 and 9, the illustrated embodiment of the invention isshown on a reduced scale and respectively in plan view, front elevationand side elevation. As there shown, the water delivery piping 19 isprovided with a control valve 32 which is adapted to be actuated by apedal 33, located at one side of and adjacent to the forward portion ofthe base or pedestal 11. As shown, the pedal 33 is located adjacent tobut to the rear of the forward face of the pedestal 111 so as to retainclear floor space below and on each side of the pan or forward extension7. The pedal is operatively coupled to the actuating handle 34 of thevalve 32 by a more or less conventional arrangement of link and lever.The pedal 33 is so located that it is convenient to the lefit heel ofthe individual using the fixture.

One aspect of our invention involves the provision for flushing thereceptacle of a fixture such as illustrated, 1. e., a fixture whichincludes a substantially round bowl and a relatively long narrowrectangular extension thereof, where the extension projectssubstantially radially of the bowl and joins the same at a point suchthat the bottom of the extension is well above the bottom of the bowl.To accomplish complete flushing and adequate washing of the entire innersurface of the receptacle, water is delivered substantially around theentire rim of the receptacle and is so delivered as to create adownwardly directed swirling sheet of water within the bowl and adiagonally directed flow of water across the bottom of the extensionwhich moves into the bowl at an angle to the radius of the bowl at everypoint of flow from the extension to the bowl, and in a direction suchthat it contributes to the swirling movement of the water moving towardthe bottom of the bowl.

While we have described but one embodiment of our invention, it will beapparent to those skilled in the art that the water receiving chamber 17may communicate with any source of water supply and that variouschanges, modifications, additions to and omissions from the structuraland functional details of the fixture illustrated may be made withoutdeparting from the spirit and scope of the invention as defined by theappended claims.
